I've been using RHP only. Creates a nice ambient temperature sweep across my cage. Just outside and on top of one of his hides will be around 90-92. If I read my BP's skin temp inside his warm hide, he's usually around 88, floor temp also. My cage is only 12 inches high. 36x24x12. There are 2 hides...one on cool side, one on warm side. THen if he wants to hang someplace else...he usually will just tunnel under the paper towel. Not often, but he will.
